Mountain Lion Parental Control time limits are not "turning off" the computer when my kids time is up
I use the Parental Controls to limit how much time my kids spend on the computer. Since I installed Mountain Lion their account is not "turning off" when the time limit is reached. They are being allowed to stay on, it appears to be indefinitely. When the log out and try to log back in it indicates that because of Parental Controls they cannot until the next day. This worked perfectly with Lion. Am I missing a setting or something?
